The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libtiff: Heap-based buffer over-read in bmp2tiff (CVE-2017-9117)

  - LibTIFF 4.0.3 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a     crafted TIFF image to the (1) checkInkNamesString function in tif_dir.c in the thumbnail tool, (2)     compresscontig function in tiff2bw.c in the tiff2bw tool, (3) putcontig8bitCIELab function in     tif_getimage.c in the tiff2rgba tool, LZWPreDecode function in tif_lzw.c in the (4) tiff2ps or (5)     tiffdither tool, (6) NeXTDecode function in tif_next.c in the tiffmedian tool, or (7)     TIFFWriteDirectoryTagLongLong8Array function in tif_dirwrite.c in the tiffset tool. (CVE-2014-8127)

  - LibTIFF prior to 4.0.4, as used in Apple iOS before 8.4 and OS X before 10.10.4 and other products, allows     remote attackers to cause a denial of service (out-of-bounds write) via a crafted TIFF image.
    (CVE-2014-8128)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

According to the versions of the libtiff packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A heap-based buffer overflow flaw was found in libtiff     in the handling of TIFF images in libtiff's TIFF2PDF     tool. A specially crafted TIFF file can lead to     arbitrary code execution. The highest threat from this     vulnerability is to confidentiality, integrity, as well     as system availability.(CVE-2020-35524)

  - An integer overflow flaw was found in libtiff that     exists in the tif_getimage.c file. This flaw allows an     attacker to inject and execute arbitrary code when a     user opens a crafted TIFF file. The highest threat from     this vulnerability is to confidentiality, integrity, as     well as system availability.(CVE-2020-35523)

  - In LibTIFF 4.0.7, a memory leak vulnerability was found     in the function OJPEGReadHeaderInfoSecTablesQTable in     tif_ojpeg.c, which allows attackers to cause a denial     of service via a crafted file.(CVE-2017-9404)

  - In LibTIFF 4.0.7, the program processes BMP images     without verifying that biWidth and biHeight in the     bitmap-information header match the actual input,     leading to a heap-based buffer over-read in     bmp2tiff.(CVE-2017-9117)

  - LibTIFF version 4.0.7 is vulnerable to a heap-based     buffer over-read in tif_lzw.c resulting in DoS or code     execution via a crafted bmp image to     tools/bmp2tiff.(CVE-2017-5563)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the libtiff packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - There is a reachable assertion abort in the function     TIFFWriteDirectoryTagSubifd() in LibTIFF 4.0.8, related     to tif_dirwrite.c and a SubIFD tag. A crafted input     will lead to a remote denial of service     attack.(CVE-2017-13727)

  - There is a reachable assertion abort in the function     TIFFWriteDirectorySec() in LibTIFF 4.0.8, related to     tif_dirwrite.c and a SubIFD tag. A crafted input will     lead to a remote denial of service     attack.(CVE-2017-13726)

  - In LibTIFF 4.0.8, there is a memory leak in tif_jbig.c.
    A crafted TIFF document can lead to a memory leak     resulting in a remote denial of service     attack.(CVE-2017-9936)

  - In LibTIFF 4.0.7, a memory leak vulnerability was found     in the function TIFFReadDirEntryLong8Array in     tif_dirread.c, which allows attackers to cause a denial     of service via a crafted file.(CVE-2017-9403)

  - LibTIFF 4.0.7 allows remote attackers to cause a denial     of service (divide-by-zero error and application crash)     via a crafted TIFF image, related to     libtiff/tif_ojpeg.c:816:8.(CVE-2016-10267)

  - tiffsplit in libtiff 4.0.6 allows remote attackers to     cause a denial of service (out-of-bounds read) via a     crafted file, related to changing td_nstrips in     TIFF_STRIPCHOP mode.(CVE-2016-9273)

  - LibTIFF 4.0.7 has an invalid read in the _TIFFVGetField     function in tif_dir.c, which might allow remote     attackers to cause a denial of service (crash) via a     crafted TIFF file.(CVE-2017-9147)

  - Stack-based buffer overflow in the _TIFFVGetField     function in libtiff 4.0.6 and earlier allows remote     attackers to crash the application via a crafted     tiff.(CVE-2016-5318)

  - An issue was discovered in LibTIFF 4.0.9. There is a     NULL pointer dereference in the function LZWDecode in     the file tif_lzw.c.(CVE-2018-18661)

  - TIFFWriteScanline in tif_write.c in LibTIFF 3.8.2 has a     heap-based buffer over-read, as demonstrated by     bmp2tiff.(CVE-2018-10779)

  - The OJPEGReadHeaderInfoSecTablesDcTable function in     tif_ojpeg.c in LibTIFF 4.0.7 allows remote attackers to     cause a denial of service (memory leak) via a crafted     image.(CVE-2017-7594)

  - LibTIFF 4.0.7 allows remote attackers to cause a denial     of service (divide-by-zero error and application crash)     via a crafted TIFF image, related to     libtiff/tif_read.c:351:22.(CVE-2016-10266)

  - Buffer overflow in the readgifimage function in     gif2tiff.c in the gif2tiff tool in LibTIFF 4.0.6 allows     remote attackers to cause a denial of service     (segmentation fault) via a crafted gif     file.(CVE-2016-5102)

  - tif_read.c in LibTIFF 4.0.7 does not ensure that     tif_rawdata is properly initialized, which might allow     remote attackers to obtain sensitive information from     process memory via a crafted image.(CVE-2017-7593)

  - A NULL Pointer Dereference occurs in the function     TIFFPrintDirectory in tif_print.c in LibTIFF 4.0.9 when     using the tiffinfo tool to print crafted TIFF     information, a different vulnerability than     CVE-2017-18013. (This affects an earlier part of the     TIFFPrintDirectory function that was not addressed by     the CVE-2017-18013 patch.)(CVE-2018-7456)

  - _TIFFCheckMalloc and _TIFFCheckRealloc in tif_aux.c in     LibTIFF through 4.0.10 mishandle Integer Overflow     checks because they rely on compiler behavior that is     undefined by the applicable C standards. This can, for     example, lead to an application crash.(CVE-2019-14973)

  - tif_getimage.c in LibTIFF through 4.0.10, as used in     GDAL through 3.0.1 and other products, has an integer     overflow that potentially causes a heap-based buffer     overflow via a crafted RGBA image, related to a     'Negative-size-param' condition.(CVE-2019-17546)
